DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 780,838, dated January24, 1905.

Application iiled June 2, 1904. Serial No. 210,833.

'To all whom, t may concern:

Be it known that I, CHARLES H. TAYLOR, a citizen of the United States,residing at Wren,

vin the county of Benton, State of Oregon,

have invented certain new and useful Improvements in Draft-Equalizers;and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will 4 enable others'skilled in the art to which it appertains to .make and use the same.

rIhis invention relates to draft-equalizers, and has for Aits object toprovide an equalizer for use with four or six horses, as desired, andwhich may be quickly changed to accommodate either number of horses.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a top plan view of the equalizer arranged for six horses.Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a view similar to Fig.1, showing the equalizer arranged for four horses. Fig. 4 is a sideelevation of Fig. 3.

vReferring now to the drawings, there is shown the beam 5 of the plow,to which is connected a" chain 6, having a vertical clevis 7, pivotallyconnected at its'center to the free end thereof, and removably connectedwith the upper end of the clevis, by means of a chain 8, is aswingletree 9, having hooks 10 attached to its ends, and connected withthese hooks, by means'of chains 11, are rods 12 and 13, which areconnected at their free ends by means of a chain 14, having split ringsor hooks 15 adjacent to its ends, which permit removal of a portion ofthe chains from the rods, and engaged with' two of the links of thechain are the reduced ends 16 of a spread-bar 17, which hold the freeends of the rods 12 and 13 separated. The spread-bar has perforations17/ in its ends, which lie beyond the links of the chains with which'these ends are engaged, and engaged with perforations are pins 18, whichprevent displacement of the bar.

Engaged with the central link 19 of the chain 14 is a yoke 20, betweenthe spaced portions 21 and 22 of which there is pivoted adjacent to oneof its ends adoubletree 23, having yokes 2 4 and 25 at its ends, andwith the latter there is connected, by means of a split link 26 and yoke27, a second doubletree 28, to the Vends of which there are connectedfor horizontal pivotal movement swingletrees 29 and 30, and to the yoke24 there is connected,l .5 5

by means of a chain 31, a similar swingletree 32. Attached to the endsof the swingletrees are trace-hooks 33. I

.Removably connected to the lower end of the clevis 7, by means of achain 34, is a doubletree 35, the chain being attached thereto adjacentto one of its ends, and pivotally and removably connected with this endof the doubletree is a doubletree 36, similar to the doubletree 28, andwhich has pivoted to its ends swingletrees 37 and 38, similar to theswingletrees 29 and 30, the swingletree 38 lying between the planesoccupied lby the rods 12 and 13, and connected to the remaining end ofthe doubletree 35, by means of a chain 39, is a 7O swingletree 40,similar to the swingletree'32. The swingletrees 37, 38, and 40 are eachprovided with trace-hooks 41 at their ends, and it will be seen that thearrangement of the doubletrees 35 and 36 and. the swingletrees 37, 75

38, and 40 is identical with that of the doubletrees 23 and 26 and theswingletrees 29, 30, and 32.

Inv hitching the horses to the equalizer one horse is hitched to each ofthe swingletrees, 8O

the horse which ishitched to the swingletree 38 being between the rods12 and 13, and connected to the collar or breast-strap, as the case maybe, of this horse are the ends of chains 42 and 43, which are passedthrough-links of -85 the chain 14- and are connected at their remainingends to the collars or breast-straps of the horses which are hitched tothe swingletrees 37 and 40. It will thus be apparent that the two pairsof doubletrees 35 and 36 and 23 9 an equalizer for four horses, theswingletree 9 and the doubletree 35 are detached from the clevis 7, andby disengaging the chains 11 -from the hooks 10 and the hooks 15 fromthe chains 14 the rods 12 and 13 may be'disengaged from the remainingparts, and one of these rods then has its chain l1 engaged with theupper end of the clevis 7, a hook being provided for this purpose. Thesplit link 26 is then disengaged from the yoke 27, which disconnects thedoubletree 28, and the yoke 27 is then engaged with the hook l5 at thetorward end of the rod. The doubletree is then disconnected from thelower end of the clevis 7, and the doubletree 36, which has beenpreviously disconnected from the doubletree 35, is connected to thelower end of the clevis 7 by means of a split link 36. The swingletrees37, 8S, 29, and 3() are thus disposed for the attachment of horsesthereto and the fourhorse equalizer is formed.

In practice modifications of the specific con: struction shown may bemade and any suitable materials and proportions may be used for variousparts without departing from the spirit of the invention.

What is claimed isl. In a draft-equalizer, the combination with a clevisarranged for pivotal attachment at its center with a vehicle, of aswingletree Vremovably connected with one end ot the clevis, rodsremovably connected with the ends ot' the swingletree and extendingforwardly therefrom, a chain removably connected at its ends to theforward ends of the rods, a spacebar disposed with its ends engaged inthe links of the chain adjacent to the ends of the rods Yto hold saidrods in spaced relation, a doubletree connected to the chain, a seconddoubletree removably connected to one end of the doubletree, aswingletree connected to the remaining end of the first-nameddoubletree, a

doubletree removably connected with the remaining end of the clevis, adoubletree removably connected with one end ol' the third doubletree,and a swingletree connected to the remaining end of the thirddoubletree.

2. A draftequalizer comprising a clevis arranged for connection at itscenter vertically to a vehicle for pivotal movement, a swingletreeremovably connected to the upper end of the clevis, rods removablyconnected to the ends of the swingletree and adapted to be disengagedtherefrom and to be engaged with the upper end of the clevis, adoubletree removably connected with the lower end ol the clevis, adoubletree removably connected with one end of the iirst doubletree andadapted for attachment at times to the lower end ol the clevis,swingletrees connected to the ends of the second doubletree, aswingletree connected to the remaining end ole the first double tree, athird doubletree removably connected with the free ends of the rods, afourth double` tree removably connected with one end of the thirddoubletree and adapted for connection at times with the free ends of therods, swingletrees connected with the ends ol the lastnamed doubletree,and a swingletrce connected with the remz'tining end oi the thirddoubletree.

In testimony whereof I aiix my signature iu presence of two witnesses.
